Thanks for the info Ingemar
I don't know if I will be able to port my game to Mac OS X any time soon - I don't have any Mac hardware, and haven't been able to get OS X working in a virtual machine to test either

That will have to wait for some future time

On the upside, I have gotten it to work on Windows and now Linux (Ubuntu), Yay! This is thanks to me using SDL, OpenGL, and OpenAL

cheers,
Paul
